Correct Answer: B

Rationale: The most indicative behavior of a 2-year-old experiencing the initial phase of separation anxiety due to parents not staying all day at the hospital is crying when his parents leave. This behavior is a common manifestation of separation anxiety in children, as they struggle with the absence of their primary attachment figures. Choices A, C, and D are less indicative because withdrawing from the nursing staff, lying quietly in bed, or crying when parents arrive do not specifically demonstrate the distress caused by separation from parents, which is the hallmark of separation anxiety in children.

Correct Answer: B

Rationale: Type 2 diabetes mellitus is most likely the result of heterogeneous risk factors, such as lifestyle choices and genetics, making it preventable. Type 1 diabetes, on the other hand, is an autoimmune condition that is not preventable. Gestational diabetes occurs during pregnancy and is not entirely preventable. Type 1 and 2 diabetes are distinct conditions, with Type 2 being the type associated with preventable risk factors.

Correct Answer: B

Rationale: The priority nursing diagnosis for a child diagnosed with an ear infection and experiencing nighttime awakenings and crying would be 'Pain related to ear infection.' Pain management is crucial to ensure the child's comfort and well-being, which can also impact their sleep patterns. Addressing the pain as a priority can lead to improved sleep and overall recovery for the child.

Correct Answer: D

Rationale: When preparing a sibling to see their brother in the pediatric intensive care unit after a near-drowning accident, it is essential to cover tubes and wires with a sheet, wash off any existing blood, and explain what the sibling will see. This approach helps the sibling understand the situation better and prepares them emotionally for the encounter, reducing potential distress and trauma. By providing information and visual preparation, the sibling can have a more controlled and less overwhelming experience when visiting their brother in the intensive care unit. Choice A is incorrect as informing the child that this could be the last time he sees his sibling may cause unnecessary distress and anxiety. Choice B is incorrect as it dismisses the sibling's emotional response, which is essential to address in a supportive manner. Choice C is incorrect as honesty and appropriate information sharing are crucial, even in difficult situations, to help the child cope effectively with the circumstances.

Correct Answer: A

Rationale: Hypopituitarism is characterized by linear growth retardation with skeletal proportions normal for chronologic age. This means that although the child experiences growth retardation, their skeletal proportions are appropriate for their age, which distinguishes it from other conditions like precocious puberty or equal height and weight affectation. Choice B is incorrect as hypopituitarism does not involve precocious puberty. Choice C is wrong as it describes a different growth pattern not typical of hypopituitarism. Choice D is also incorrect as in hypopituitarism, height and weight are not equally affected, rather the focus is on linear growth retardation with normal skeletal proportions.
